Project: Flink
Issue Type: Bug
Components: Table API & SQL
Affects Versions: 1.3.2, 1.4.0
Reporter: Fabian Hueske

Fix For: 1.4.0, 1.3.3
A Table with a time attribute ({{TimeIndicatorTypeInfo}}) cannot be written to
a {{CsvTableSink}}.
Trying to do so results in the following exception:
{code}
Exception in thread "main" org.apache.flink.table.api.TableException: The time
indicator type is an internal type only.

The time attribute should be automatically converted into a {{SQL_TIMESTAMP}}
type.
